n FOLDING BOX.

i application med octber 19, 192s. serial No. Magne.

This invention relates to an improved folding box of the multi-cell type which is especially,.but not necessarily, adapted for containing eggs, individual articles of fruits,

et cetera.

Brieiiy, the invention has reference to an improved foldable box made from a single blank of-v paper board or similar material, together with a cell unit, said unit being connected with said box insuch a way as vto move into cell forming position when the blank is spread out flat and ready to be folded up to make a complete box surroundin'g it. Y Y It is my primary purpose, to generally improve upon structures of this class by pro- -v iding one of comparative vsimplicity and, durability wherein the details are novel and are associated in a novel manner forming an improved product of manufacture which is entirely satisfactory from a standpoint of use and also from a standpoint of handling andvshipping due to the compa'ctness and convenience of arrangement.

@ther features and advantages of the invention will become apparent from the following description and drawings. n

In the accompanying drawings forming a part of this application and in which like 30. numerals are employed to designate like i parts throughout the same Fig. 1 is a perspective view of the struc- ,ture readyfor use. l

Figure 2 is a longitudinal section through the same.

Fig. 3 is a central transverse section.

y Fig. 4 is a View` showing the cell unit in operative position with the portions of the box lying flat and ready to be folded up into forming relation.

Fig. 5 is a view showing the bottom half in the structure in Fig.V 4 folded over onto the remaining or complemental half for'convenience of Vpacking .and shipping.

Fig. 6 is a detail perspective View showing the association of the cell forming partition more plainly. y

Referring to the drawings in detail it will be seen that the reference character 1 designates generally the box whereas the reference character 2 designates the Cell unit. Considering first the box it will be seen that this vis formed from a single blank of cardboard which has a plurality of spaced parallel fold lines dividing into a rectangular bottom section 3, a correspondingly shaped top section 4, and side sections 5 andl 6, respectively. The top section carriesa central extension 7 forming a retainer which is adapted to be inserted through a slot 8 formed in the front side section 6, thelast-nalned section is provided with a foldable flange 9 adapted to underlie the free edge of the top section 4. The blank also includes duplicate end walls 10 shown :better in Figs. 1 and 52 At this time I would direct` attention to the fact that ythe ree'edges of the end walls 10 are pro- 'vided w1th notches 1l andl inward of these .with substantially T-shaped `openings 16.

The complementa] longitudinal .partition pieces 13 are provided with intermediate slots of a peculiar formation as represented better in Fig. 2. Referring to this ligure it will be seen that these slots open through the bottom edges and formed on one edge of the slot is an inwardly extending lockingtongue 17 for cooperation with the T-shaped opening 16. The portion of this edge below the tongue is cut away to provide: clearance as represented at 18. The opposite edge of the slot is formed with a longitudinally curved portion 19 and terminates in an abutment 20. With this arrangement it isl obvious'that the tongues 16 are permittedto extend into interlocking relation with the T-shaped slots thus connecting the partitions together as indicated in Fig. 2 and permitting them to be. folded.. The ends of each longitudinal partition are formed to provide depending extensions 21 carrying inwardly extending tongues 22to fit into the aforesaid openings 12 in the end walls 10. The Slots 19 which co-operatewith these .depending extensions 21,-are,of reverse Aformation when compared with the other slots 19; that is, they curve inwardly to provide clearance spaces for the project-ing tongues 22.

In forming the improved product, the cell unit 2 is assembled upon the box 1 as shown more plainly in Fig. 4. As indicated in that figure, the tongues 22 on the ends of the longitudinal partitions 13 `areengaged with the slots or `notches 11 and the openings 12, permitting the tongues 22 to project throughY the openings 12. The partitions and cells are connected together by inserting the solid web portion of the partition-13 into the flared notches 15 and then engaging the tongues 17 with the T-shaped opening-s 16. Assuming that the' cell unit is attached 'to the bottom 3 of the box as explained, it

is obvious that the side walls 5 and 6 are folded up against the longitudinal edge portion of the unit and that the. iiange 9 is folded over top of one edge portion, while the top section 4 is moved into overlapping relation with this flange as represented in Fig. 3. Then the exten-sion 7 is inserted in the slot 8 and the box is maintained in closed position. Attention is now directed to a central longitudinal fold line 23 which intersects the first-named fold lines at about the` centers of the same. This allows the blank to be folded 'into halves from the position shown in Fig. 4 to the position shown in Fig. 5. It is understood that during this folding the cell unit 2 is left in place and when the two half sections of the blank come together, this folds the cell unit substantially in halves which are shown projecting to the right of the end walls 10 in Fig. 5. This makes an exceptionally compact article and allows quick opening to the arrangement indicated in Fig. 4 for subsequent formation of the box.,

It is believed that by considering the description in connection with the drawings a clear understanding of the invention will be had. Therefore, a more lengthy description is thought unnecessary.

Minor changes coming within the field of invention claimed may be resorted to if desired.

YHaving described the invention, what is claimed as new isE- y 1. In a folding box of the type specified,

a foldable blank for making a box embodying a bottom, top, side, and end walls,

formed by individual fold'lines scored transversely on said blank, said end walls being formed with individual slots, and a. foldable cellular filler including longitudinal partitions having tongues extending through said slots and forming hinge connections between, said partitions and end walls, said blank and filler being foldable on additional fold lines into superposed halves in a direc- 'tion at right anglesto the transverse fold lines first named.

2. In a folding box of the Class described, a foldable blank formed with a plurality of transversely extending longitudinally spaced 4fold lines scored for facilitating the formation of a box including bottom, side and top walls, said blank being provided with extensions projecting beyond the ends of the bottom wall and connected to said bottom wall by fold lines permitting said extensions to be bent upwardly to form end walls for the box, a cellular filler composed of interconnected longitudinal and transverse partitions connected in intersecting relation to provide a multiplicity of cells, the ends of the longitudinal partitions extending beyond the end-most transverse partitions, and tongue and slot connections between the ends of the longitudinal partitions and the end walls of` said box for hingedly connecting said ller to said end walls, and for allowing right angular swinging movement of the longitudinal partitions with respect to said end walls, said blank being provided with a longitudinal fold line intersecting said transverse lines and said filler being foldable into half-sections at its center, whereby when said blank is folded on said longitudinal fold line into superposed halves, said filler is simultaneously folded into half sections between the longitudinal edge por-l tions of said halves.
